Abstract
The utility model provides an anti-loose washer of a rotary shaft of a generator, and belongs to the technical field of machines. The anti-loose washer solves the problems that an existing anti-loose washer cannot be easily oriented and is poor in stability. The anti-loose washer is sleeved on the rotary shaft of the generator and comprises a cylindrical washer body. The inner side of the cylindrical washer body is provided with a plurality of convex keys which are circumferentially distributed and used for being matched with key grooves in the rotary shaft of the generator. Each convex key extends along the axial direction of the washer body, and the front end of each convex key is provided with a guide portion. The anti-loose washer has the advantages of being easy to orient and high in stability and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to the check washer of a kind of check washer, particularly a kind of alternator shaft.
Background technique
The magnet steel of existing permanent magnet generator is screwed in the rotating shaft surface, be drilled with tapped hole to facilitate the installation of screw on the rotating shaft surface, cause the rotating shaft surface crackle to occur, the working procedure shaft vibrates for a long time, easily fatigue break, magnet steel is also frangible, causes its working life short, and concentricity is relatively poor.
problem for above-mentioned rotating shaft existence, the applicant has invented a kind of rotor structure of permanent magnet generator, it comprises rotating shaft, be set in successively the pad in this rotating shaft, head plate one, magnet steel and head plate two, pad is fixedly installed in rotating shaft, head plate one is resisted against on this pad, magnet steel is resisted against on head plate one, head plate two is resisted against on this magnet steel, and then by a locking nut, head plate two is locked, have some rotor sheets that are set in rotating shaft between head plate one and head plate two, have two shrinkage pools that relatively arrange on rotor sheet, magnet steel is embedded in this shrinkage pool.Consider that said structure need to be circumferentially fixing with rotating shaft, spline shaft structure is arranged in rotating shaft.There is no screw in this rotor structure, can not crack, because rotor sheet is enclosed in the inside with magnet steel, even the overall structure of the cracked rotor of magnet steel is unaffected.Because pad is not standard piece, cause the pad on market can not be used in this rotor structure, therefore the check washer of the rotor structure special use of this permanent magnet generator need to be provided.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed that a kind of stability is high, the check washer of the alternator shaft of reasonable in design.
The purpose of this utility model can realize by following technical proposal:
A kind of check washer of alternator shaft, be set in the rotating shaft of generator, comprise tubular body, it is characterized in that, the inboard of described body has the protruding key that matches with keyway on alternator shaft of being used for of some circumferential distributions, described each protruding key extends axially along body, and the front end of described protruding key has guide portion.
In use, the body cover is set in rotating shaft, coordinates with spindle keyway by protruding key, can prevent effectively that body from circumferentially rotating with respect to rotating shaft; The front end of this protruding key has guide portion, and the body cover is set in rotating shaft in a flash, can lead to body, and is easier for installation.
In the check washer of above-mentioned a kind of alternator shaft, the rear end of described body has the stop part that radially protrudes, and the front side of described stop part has chamfering.This stop part has increased the area of contact of body and magnetic steel structure, can effectively carry out spacingly to magnetic steel structure, prevents that it from moving axially.
In the check washer of above-mentioned a kind of alternator shaft, above-mentioned protruding key is extended to the medium position place of body by the rear end of body, and described some protruding keys evenly distribute.
In the check washer of above-mentioned a kind of alternator shaft, the quantity of described protruding key is 2-8.
In the check washer of above-mentioned a kind of alternator shaft, the quantity of described protruding key is 6.
Compared with prior art, the check washer of this alternator shaft has the following advantages:
Increase protruding key in body, circumferentially fixing with alternator shaft, the stability that rotating shaft is rotated is improved, and have stronger directing effect, prevent that magnetic steel structure from moving axially along rotating shaft, effectively extended the working life of alternator shaft.
Description of drawings
Fig. 1 is the structural representation of a kind of preferred embodiment of providing of the utility model.
Fig. 2 is the sectional view at A-A place in Fig. 1.
In figure, 1, body; 2, protruding key; 21, guide portion; 3, stop part; 4, chamfering.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, the check washer of this alternator shaft is set in the rotating shaft of generator in use.This check washer comprises tubular body 1, the inboard of body 1 has the protruding key 2 that matches with keyway on alternator shaft of being used for of some circumferential distributions, each protruding key 2 extends axially along body 1, and as shown in Figure 2, the front end of each protruding key 2 has guide portion 21.
As shown in Figure 2, the protruding key 2 in the present embodiment is extended to the medium position place of body 1 by the rear end of body 1, and some protruding keys 2 evenly distribute.In use, body 1 cover is set in rotating shaft, coordinates with spindle keyway by protruding key 2, can prevent effectively that body 1 from circumferentially rotating with respect to rotating shaft; The front end of this protruding key 2 has guide portion 21, and body 1 cover is set in rotating shaft in a flash, can lead to body 1, and is easier for installation.
As depicted in figs. 1 and 2, the rear end of body 1 has radially the stop part 3 that protrudes, and the front side of described stop part 3 has chamfering 4, and this stop part 3 has increased the area of contact of body 1 with magnetic steel structure, can effectively carry out spacingly to magnetic steel structure, prevents that it from moving axially.
In actual use, the quantity of protruding key 2 can be arranged to 2-8, in the present embodiment, as shown in Figure 2, the quantity of protruding key 2 is set to 6, forms the gap between each protruding key 2.
The check washer of this alternator shaft is at the protruding key 2 of the interior increase of body 1, circumferentially fixing with alternator shaft, the stability that rotating shaft is rotated is improved, and have stronger directing effect, prevent that magnetic steel structure from moving axially along rotating shaft, extended the working life of alternator shaft.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
